HOW TO CONDUCT THE STATIONARY SOUND TEST This is a summary of the SAE J1287 JUL98 stationary sound Test Site test procedure. Although stationary test measure primarily No one should be within 10 feet (3 meters) of the vehicle exhaust noise, this test has been designed to pass quiet other than the rider, the sound meter operator, an assistant to vehicles (those which test below a specified limit) and fail hold the front of the vehicle(if needed) and one other person those that exceed a certain sound level limit. directly behind the sound meter operator(if needed). This procedure may be used to allow motorcycles and The test area should be a flat, open surface free of large ATVs to enter an OHV park, as a prerequisite for entry into sound-reflecting surfaces within 16 feet (5 meters), such as a competitive event, or to support enforcement actions for parked vehicles, buildings, signs, and hillsides. those vehicles subjectively observed as being too loud. The surface should be free of loose soil, snow or grass higher Sound Test Equipment than 6 inches (150 millimeters). For convenience, attach a 20-inch string to the front of the The ambient sound level (including wind effects) at the sound level meter for the stationary sound test. site shall be at least 10dB lower than the sound level of the vehicles tested. Do not use a stick or wire for this purpose as the sound level reading may be affected. Always use a windscreen under windy conditions. The stationary test procedure should not be conducted if the wind Allow the sound level meter to come to the same temperature speed is 20 mph (9m/s) or higher. as the surroundings. If it is necessary to test in higher winds, position the vehicle Set sound level meter to the slow dynamic response and the so the wind direction is parallel to the normal direction of A-weighting network (if equipped with this option). travel of the vehicle. 209 Also, do not attempt sound level measurement when it is Set the vibrating reed tachometer to the test RPM, or attach raining or snowing. an electric tachometer. Measuring the Vehicle Sound Have the rider or assistant hold the vibrating reed tachometer Make sure the engine is warmed up and the transmission is in against any solid part of the vehicle, or have the rider or neutral. assistant read the meter of the electric tachometer. Have the vehicle operator slowly increase the engine speed Have the rider sit on the motorcycle with both feet on the to the test RPM. ground, or on the ATV with feet on the footrests, so that the vehicle is vertical and stationary. Have the vehicle operator or assistant signal when the correct RPM is held (e.g., by tapping his foot). Hold the sound meter: Read the sound level meter when the correct RPM is held. 1.

The closing RPM (according to the Federal Test RECOMMENDED SOUND LIMITS Procedure) contained on the “Motorcycle Noise The Motorcycle Industry Council, Inc.

To the following maximum sound limit, based on the stationary determine one-half of the maximum rate RPM from sound test procedure (SAE J1287): the closing RPM value on the motorcycle label, use the appropriate formula below: Motorcycles & ATVs Maximum Sound Level General Off-Highway 96 dB(A) with Engine Size 1⁄2 Maximum Rated RPM Use (SAE J1287) 0-175 cc “Closing RPM” divided by 1.9 Closed-Course The sound limits estab Competition Events lished by the organization 176-675 cc “Closing RPM” sanctioning the event should divided by [2.18-(.0016 x be followed. engine size in cc)] The 96 dB(A) limit is recommended as the maximum in Over 675 cc “Closing RPM” areas where no sound level laws exist.
